The DME system, which has found wide spread worldwide application in the civil and military area as well, includes, due to its ingenious signal format and the very economic channeling scheme, a considerable potential for additional applications. Today's navigation and air traffic control systems have at least partly reached their limits of improvement and extension as the call for a Microwave Landing System (MLS) proves. The growth potential of the ICAO-standardized Distance Measuring Equipment (DME) allows for various operational extensions by improving the distance measuring system to Precision Distance Measuring System (PDME) and using DME interrogations by direction finders on the ground, measuring azimuth and elevation. The operational applications of these features are the DME-based Landing System (DLS), the FRGs contribution to the international MLS competition of ICAO, the additional use of the DLS-A ground subsystem as TMA-navaid, the extension of this principle to the enroute-navigation called DENS for DME-based Enroute Navigation System, the universal DLS/DME/DENS = DLENS airborne equipment, and last but not least the step into the ATC/CAS-field with DACS (DME-based Air traffic Control System). The paper explains the systematic and technical background of this aeronavigational system. An analysis of the various subsystems detailing these advantages compared to today's installations dealing with the areas of operational performance and economic efficiency mainly, is given.
